GeForce GTX 465 vs GeForce GTX 560 Ti

Intro

Compare all of that to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 RAM is set to run at a frequency of 1002 MHz on this card. It features 384 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti		170 Watts
GeForce GTX 465		200 Watts
	Difference: 30 Watts (18%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti will be 25% faster than the GeForce GTX 465 overall, due to its higher bandwidth. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 25664 (25%)

Texel Rate

The GeForce GTX 560 Ti is quite a bit (about 97%) better at AF than the GeForce GTX 465. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 25900 (97%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 Ti is the winner, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 6880 (35%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
